Humans have such duh ears! I am really jealous of wildlife who have decent sound detectors. In fact, I spent one whole session meditating, journaling and sketching about our rotten ears and my Do-It-Yourself invention to put us humans on a slightly more level playing field.
Here is the journal page for your enjoyment. I hope it gives you a giggle, because I had a lot of fun creating it.
Of course, as I was sitting out in the woods at the time I did it, I looked up (and listened up!) frequently to make sure I wasn't missing anything. And since it was a VERY quiet day, without any passing-through deer or brouhaha in the bird world overhead, and with nothing but mosquitoes pestering me, I had plenty of time to devote to this important page.
So, click on the image to get a readable size, and I beg of you, experiment with your ears for a few minutes to find out what I'm talking about ~ and then maybe even make yourself a decent 'Earing Aid as shown. NOTE: If you are a Grown-Up, abandon your dignity and try this.
All you need is one or two yogurt containers or paper cups, a pair of scissors, and some glasses ~ an old pair of specs without any lenses in them will work just fine. If you (or your kid) wear glasses, you have an instant advantage.
Cut the cup as shown, flatten it on the side that will go next to your head (a paper cup would have the advantage here, but you can just lightly squash a plastic yogurt cup with pretty good results) hook it over your ear, and slide the glasses on, poking the earpiece THROUGH the big end of the cup and out the "bottom."
And then, go outside and play. It's a lot of fun, and if you have kids, they'll have a blast with it! Especially if you do it with them. Try whispering to each other across the yard. How far away can you hear a whisper?
